Young students do not always have the maturity and the perspective to make enlightened choices (and parents, are often clueless). There is a lot of denial when it comes to studying with a coach that has success but also, may have dubious training methods. It's not only in figure skating. It happens in many other sports and fields.
The issue I see in this particular case is exactly that : because there is a large pool of talent, not every skater really matters... training methods can aim at creating winners but don't need to nurture the athletes in all aspect of sport, including physical health and mental health. What this creates, is exactly what has been witnessed... winners- yes, shorter careers- yes, and many many injured kids. It puts the coach above the athlete... not the other way around. The athletes serve the coach instead of the coach serving the athletes. Fine, the winner may feel that they received good and optimal coaching. But the other 99 kids ? Nope.. because this culture in coaching has only ONE goal... Winning, and doing so as fast and quickly as possible.
In some other parts of the world, the pool of talent is limited. Athletes have to be nurtured and cared for. Yes, injuries can always happen. It's a dangerous sport after all. However, there are places where having fun, being healthy while practicing an elite sport, and personal and human growth are valued. It's a cultural shift that is definitely happening. I see it also happening in other fields (like performing arts). One can simply look at emerging talent from countries where healthy methods are used... In the long term, it does create better artists and longer careers.
The child prodigy culture is definitely not something sustainable... It has always been impressive for people to see kids play a Rachmaninoff concerto or jump a quad at a tender age... but everyone grows up... and aiming to work in a different learning curve creates better artists and healthier athletes... I am convinced that coaches can evolve and adapt their learning curve... Some do so... Some just don't care to do so. They know one and only one way to make it work.
I am okay with people fantasizing about child prodigies in some disciplines.. not my cup of tea.
However, I am not okay with children getting hurt physically and psychologically, and in figure skating, the child prodigy culture is particularly dangerous.
